A clinical diagnosis of metastatic bone tumors is usually based on radiological findings without bone biopsy. Plasmacytoma can present as a single osteolytic lesion as described in this case. Early bone biopsy should be considered in unusual clinical settings for a differential diagnosis of primary bone tumors.
Sternal tumors are very rare and challenging. Secondary sternal tumors are more common than primary tumors. These tumors are usually refractory to chemotherapy and radiotherapy, and surgery is the best choice for their treatment. In this study, we reported the collected data of 15 patients with primary and secondary tumors of the sternum, histological type, as well as kind of resection and reco...
Although widespread skeletal dissemination is a critical step in the progression of myeloma, little is known regarding mechanisms that control metastasis of this cancer. Heparanase-1 (heparanase), an enzyme that cleaves heparan sulfate chains, is expressed at high levels in some patients with myeloma and promotes metastasis of some tumor types (eg, breast, lymphoma). Using a severe combined imm...
Background and Aim: Osteoblastoma is one of the rarest primary bone tumors. Although, small bones of the hands and feet are the third most common location for this tumor, the hand involvement is very rare and few case observations were published in the English-language literature. Materials and Methods: In this study, we report five cases of benign osteoblastoma of the hand...
IMAGE-guided percutaneous methods of tumor destruction have proven effective for treatment of benign bone tumors as well as for palliation of metastases involving bone and soft tissue sites beyond the liver and lung. Treatment of primary bone tumors is largely restricted to benign tumors, most notably osteoid osteomas, as a single-modality treatment or as an adjunct to surgical resection (1– 4)...
Spontaneous regression of primary malignant bone tumors is rare but has been reported in the human literature. To the authors' knowledge, spontaneous regression of primary bone tumors in dogs or cats has not been reported. Osteosarcoma (OSA) is the most common primary bone tumor in humans, and it has been reported that the incidence of OSA is 40 to 50 times greater in dogs than humans. In this ...
